Project Description

I joined the lab to work on an ANR project with the aim of investigating and understanding the recycling process of a lipid carrier, the undecaprenyl phosphate (C55-P). This carrier allows the assembly of peptidoglycan by translocating the lipid II from the cytoplasm to the periplasm thanks to the flippase MurJ. However, while it has been previously established two classes of phosphatases take part in that process, the recycling of C55-P is only partially known. Our goal is to determine the localisation of these membrane phosphatases in E. coli in order to understand the interplay between them and the peptidoglycan biosynthesis machineries by using recombinant fluorescent proteins and microscopy.
